IMPROVEMENT IN LAMP-CHIWINEV SUPPORTERS.

Specification forming part of Letters Patent No. 140,214, dated .I une24, 1873 application filed March 22, 1873.

To all whom it may concern:

Be it known that we, WILLIAM MEARs and HENRY DAvIEs, of Newport, in thecounty of Campbell and State of Kentucky, have invented a new andImproved Globe Chimney- Supporter, of which the following is aspecification:

In the accompanying drawing, Figure l is a vertical section of ourimproved chimneysupporter as applied to center-lamps ou the line o c,Fig. 2. Fig. 2 is a side view ot the same. Fig. 3 is a vertical sectionof a wedge clamp-supporter, also applied to center-lamp. Fig. 4 is aside view of the same as applied to side lamps. Fig. 5 is a verticalsection, and Fig. 6 atop view of the wedge-clamp of the same.

Similar letters of reference indicate corresponding parts.

The object of our invention is to construct a device by which the globesof side and center lamps' of railway passenger-cars may be easilychanged without disturbing the lamps, for the purpose of cleaning thesame or substituting new ones without delay. The invention consists of acylindrical tube connected by brackets to the sides or top of the car,which tube incloses the sliding metallic chimney resting on the globe,and allows the same to be set to any desired position by means of wedgeor spring clamp arrangement.

In the drawing, A represents the glass globe of a center or side lamp ofa passenger-car, which has tightly fitted to its rim the metallicchimney B, which connects in the case of the former lamp with a somewhatlarger aperture, C, in the roof or top of the car, so as to extendthrough it when lifted ott', the globe also to serve as outlet for thegases of combustion. The globe chimney slides inside of a guide-tube, D,of suitable material, which is connected to the top or side of the carby means of suitable brackets E. Wedge or spring clamps operating onchimney B regulate the position of the same in guide-tube D. Thewedge-clamp, Figs. 3 to 6, is constructed by providing suitable recessesin brackets E for the admission of a wedgepiece, f, which inclines underan angle of forty-five degrees toward the chimney, and acts on itthrough a corresponding opening in guide-tube D by means of head-screwF. A

metallic piece, e, is curved to iit tightly on the chimney, and suppliedwith T-shaped projections and side pins to prevent an upward and forwardchange of position when the chimney is taken out. It is kplaced into thebracket-recess and pressed by means of wedge-piecef and head-screw Fagainst chimney B, clamping thereby the same firmly at any positiondesired. rlhumb-screw F of top center-lamps inclines downward under anangle of fortyiive degrees, enabling thereby the easy handling andadjustment from below. A reflector, G, incases the top brackets E andthe clamps, presenting a neat outward appearance. Thumb-screw F of sidelamps is placed under the same angle toward the chimney above thebracket E, and acts, by means ot' Wedge-pieces f, (curved to iit thechimney and recessed to admit the screw F,) on chimney B. Pins g,applied through the sides of bracket E to the upper part oi' wedge f,secure the position of the same and prevent the detaching from thebracket.

The spring-clamp device is shown in Figs. 1 and 2, and consists of twovertical slots, a, at the upper part of tube D, in connection with aslot, b, inclining toward them under an angle of forty-tive degrees,forming a triangular segment. Slots a must be of sufficient width toallow free play of the segment when clamped against chimney B bythumb-screw F. A projection, d, of the segment, serves as rest for screwF moving in a female screw of bracket E, and transmits the clamppressure on chimney B, sustaining it in any position till the globe ischanged, cleaned, and replaced. The chimney B rests iirmly on globe Awithout breaking or disconnecting from the same. The annoyanceoccasioned by the breaking 0f the globes and smoking ot' the lamps may,therefore, in a great measure be avoided.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- The guide-tube, bracket, and wedge-clampcombined with the chimney B, as and for the purpose described. l
